To all witom it may concern:

E. SPAULD- Be it known that I, CHARLES ING, a citizen of the United States, residing at Centralia,'in the county of Marion and. State of Illinois, have invented new and useful Improvements in Pulverizers, of which detachably coupled together, the front section being provided with the knives and the rear section bein provided with the rollers.

so that the machine may be used as a whole or may be used with the rear, roller section of the frame detached so that only the.

knives are employed to operate in the soil.

With the above and'other objects in view the invention consists in the construction, combination and arrangement of device hereinafter described and claimed. I In the accompanying drawings :Figure 1 is a plan of a combined land roller and pulverizer, constructed in accordance with my invention. Fig. 2 is a side elevation of the front portion of the machine, showing the knives and their connections. Fig. 3 is a vertical longitudinal sectional view of the same. Fig. 4 is a detail perspective view of one of the knivesand its pivoting sleeve.

The frame 1 of my improved combined land rollerand pulverizer is of oblong rectangular form :and comprises a front section 2 and a rear section 3 which are detachably coupled together. The front section comprises'front and rear bars 4-5, and bars 6, outer intermediate bars 7 and inner intermediate bars 8. These bars are preferably made of Wood and are mortised or otherwise suitably secured together and the corners of the section 2'are respectively reinforced by angle irons 9 which are secured in place by bolts 10. Angle irons 11 are also secured by loolts 12 on the bars 2--5 'and theinner intermediate bars 8. Atongue or draft'pole' 1 3 has its -rear end securedon thewcenter V CHLES E.

- of the frame section 2 by means of clips I l-15 which are respectively bolted on the bars 2.5. The bar 16 which carries the seat- 17 for the driver has its front endbolted on the rear endiof the tongue. Braces 18 are provided on opposite sides of the tongue and are bolted thereto and to the bar .4. The doubletree is indicated at 19 and is securedon the tongue by a bolt 20 this bolt passing through the front end of a strap 21, the rear end of which is secured by a bolt 22 on the tongue.

An axle shaft 23 is secured to the lower ends of V-shaped standard brackets 24 which are bolted to the under sides of the bar 6 and a central bar 25 with which the frame section 2 is provided. Supporting wheels 26. are mounted on the ends of the said axle shaft and beyond the sides of the main frame and are here shown as provided with concave rims 27 Knives 28 which are arranged parallel with the line of draft are each provided with a series of serrated teeth. 29. Each knife also has a forwardly and upwardly extending arm 30 the front end of which is secured by a bolt 31 in a cleft arm 32 at the rear side of a cylindrical sleeve 33. The-said sleeves are arranged pivotally on the axle shaft and hence serve to pivo'tally connect the knives to the axle shaft, to space the knivesapart appropriately and adapt the knives to be raised and lowered. Sleeves 34- are arranged near the ends of the axle shaft and are secured thereto by keys 35 to hold the pivoting sleeves of the knives in place. The knives are connected together by a transversely arranged angle bar 36.

Apair of shafts 37 are mounted in bearings 38 secured on the intermediate bars 7-8. Each of these shafts is provided with pulley drums 39 nearits ends and is also provided with ratchet wheels 40. Chains 41 are attached to the pulley drums and to the bar 36. Each shaft 37 is also provided at its inner end, with a lever 42 and the said levers arewithin easyreach of thepdriver so that he can use said levers to turn the secured on shafts 44 which are mounted in bearings 45 and each shaft is provided near :Goples of thisfpate nt may be obtained for its inner end with q'a' foot lever 46 for-oper-' side bars 47 and a rearcross bar 48. Rein- 5 forcing angle irons 49 are bolted on the rear corners of the frame section 3 as at 50. A front cross bar 51, whichis an. angle iron, connects the. front ends of the bars 47, angle irons 52 being boltedtoisaid 'bar 51 and 0 bars47 and being arranged in the angles be-' 'tweenith'em. A central'cross bar 53 which Bearings 56are secured by suitablebolts to the under sides and at .the centers of 'the bars 47-53;,"1A shaft 57 is mounted inthe said bearings and a pair of rollers 58 are mounted on said shaft.

When the machine is in operation the teeth 28 cut the earth longitudinally or parallel with the line of draft and the teeth of theirollerscutthe earth transversely or at rightangles to the line of draft, as will be understood', so that the earth 'is' thoroughly pulverized as well'as rolled.

The/sections of the frame are detaehably coupled together. Said sections are respectively provided with 'coupling members 64-65. which are bolted on their outer sides and are provided with interengaging 6667. Coupling pins 68 are placed in registering openings in said lugs and held in place by split keys 69. By removing the j coupling pins the sections of'the frame may lugs knives 28 to be used without also using the rollers, when this is desired. The "Vvheels 26 'with which the front section of the frame is provided carry the weight of the frame and relieve the same from the horses necks so that the horses only have to exert pull 7 'when drawing the machine. is also of iron, is also provided for the rear frame section '3'and is secured to the bars 51 and 48 by angle irons 5 455 which are bolt- 5 ed in place as 'shownQ 'Whi1e I have herein shown and described a preferred form of my invention I would have it understood, that changes may be made in the form, proportion and construc-- tion of the several parts without departing from the spirit of the invention and within the scope of the appended claims.

Having thus described my invention, I

claim 1; A machine of the class described having knives arranged parallel with the line of draft and provided at their lower sides with laterally inclined teeth.

'2. A machine of the class described having knives arranged parallel with the line of draft aild provided at their lower sides with laterally inclined teeth arranged at an angle to the line of the knives, and ex-' tending from'opposite sides of the knives. In testimony whereof I afiix my signature in presence of two witnesses.
